Paper Title - Control Strategy For Mitigating Faults in Distributed Systems by using SCESS with FDG

Abstract
This manuscript propose a flexible D-STATCOM is a new controller that be able to mitigate all types of faults
and operates like a distribution generator when it supplies power to sensitive loads while the main utility source is disjointed.
Thus D-STATCOM operates same as a flexible DG (FDG) and accordingly it is called Flexible DSTATCOM (FD-
STATCOM). The FD-STATCOM system mitigate power quality problems and all types of faults such as Line-to-Line (LL)
and Double Line to Ground (DLG) faults and supplies power to sensitive loads under islanding condition. In this thesis the
12-pulse D-STATCOM with IGBT is used and the graphic based models are developed using the PSCAD/EMTDC
simulation program. The voltage disturbances caused by LL and DLG faults and islanded operating condition are obviously
proved in the simulation results.
